The Last Sanctuary

 is a faction quest in.

Synopsis
Prince Aruihi sent an expedition to investigate Motare o Kōzi, an island once used for shelter and sanctuary in the days of Ukaizo.

Aruihi believes the location of lost Ukaizo might be recorded somewhere on the island, but his expedition has not returned.

He needs someone to learn the fate of the expedition and find the information they sought. The trading companies are doubtless sending their own forces to do the same.

Walkthrough

 * This is a straightforward quest. Acquire the Huana Chart needed by the prince, then return.
 * To access Motare o Kōzi, you must first get past the Wahaki tribesmen on the beach at Matekau Landing. The script choices that work are Diplomacy 4 or Intimidate 5, then you must either have Intimidate 7, a Druid class, a Good 3 reputation with the Huana, or have completed A Shrewd Proposition and Cruel Cargo by siding with the Wahaki.
 * Although not essential to the quest, saving Baltia gets you a pure 2-star cannoneer, worth a lot if you plan to sail a galleon or junk. Baltia, a survivor of the second Vailian expedition trapped by a crushing vine, is located to the north-northeast of the arch where you enter the grove. Saving her requires either a druid or Might 16.  If you have neither, and you might want Baltia later, avoid interacting with her. If she spots you she cries out "Help! . . . please!" -- don't let that happen.  You can return later when you have a druid or Might 16 in your party.

The key to easiest completion of the quest is healing the corrupted grove by healing the three delemgan daughters of the Rotted Lady, who guards the area, and healing the Rotted Lady herself. A violent course of action gains you nothing substantial for your effort.
 * Healing the grove


 * There are three corrupted trees around the grove, each tied to one of the Rotted Lady's daughters: one to the northwest, one to the south-southwest, and one to the east.
 * For the peaceful path, interact with each tree without killing the enemies around it. Simply stealth up to the tree and interact with it. Sparkcrackers come in handy to distract the guardians of the southernmost tree.
 * You will get a scripted encounter by clicking on the blue field at each tree. You can either use a druid character (e.g. Tekēhu) or the weapon The Spine of Thicket Green to drain the corruption from the trees. Or you may destroy the trees, which will make the Rotted Lady hostile.
 * Restoring the trees will make two of the daughters friendly, and they'll promise to help you in confronting their mother. The third daughter, to the northwest nearest her mother, at first acts angry with you because she felt strong before you healed her, and tells you what her mother will do to you.  But when you approach the Rotted Lady, this daughter also tries to convince her mother to listen to you.
 * After restoring the daughters, you can talk to the Rotted Lady, in the northwestern part of the ruins, by a fourth corrupted tree growing around an adra pillar.
 * You can restore her and the grove if during the initial conversation you ask if it's possible to heal her.
 * If you have The Spine of Thicket Green you'll get the option to offer it as a way to cleanse the grove. She'll refer to it as her cousin's limb, and you get the option to have Tekehu talk to her (though nothing will come of it) which in turn gives you a different set of lines to convince her that she and the grove are corrupted. I.e. nothing of conequence, except flavour.
 * Use Diplomacy 8 or Alchemy 6.
 * She'll claim the grove is green, healthy, full of life, a thing of beauty. Honesty will make her attack, while a Rational or [Lie]Benevolent reply will make her realize that her grove has fallen to corruption.
 * You can offer Tekehu or her cousin, The Spine of Thicket Green, as help, or offer to restore the adra pillar yourself. Then you start a scripted interaction where you can either destroy the tree or investigate, and heal, the corruption.
 * To heal the tree, you have three alternatives:
 * Whisper to the adra that is at its core and feed it soul essence to restore it.
 * Use the Spine of Thicket Green to drain the corruption.
 * Have a druid whisper to the tree and convince it to give up the corruption within. Here you will have to react to a presence within the tree, either embracing or rejecting the temptation of what the presence offers.
 * After driving the corrupting presence out of the tree, the Rotted Lady will turn into the Green Lady.
 * The Green Lady will bless you with nature's mark, identifying you as an ally of earth and nature. All remaining creatures in the area become friendly and you can easily explore the rest of the map.
 * There are three souls around the ruins, revealing the fate of the last Vailian expedition and info about the disc. If Xoti is in the party, she'll harvest these for her quest, The Lantern of Gaun, though only one entry will appear in the Journal.


 * Activating the disc
 * The ruin in the center contains the ancient Huana map disc containing the information you need for the prince. You can use Mechanics 4 to identify the workings of the mechanism. The inscription gives a rough idea of the machine's function, but you need to find the correct parts to make it work. The parts are to the northeast, in the den of the corrupted tigers, and in the northwest, by the Rotted Lady / Green Lady tree.
 * Once you place the parts, you need to activate the mechanism. You will be given four inscriptions in order of the combination :
 * Though their roots grow from Rikuhu's lightless bowels, their yield is a welcome reprieve. (koiki fruit)
 * Our covenant to safeguard. Those petrified limbs are the health and safety of the Deadfire. (luminous adra)
 * Ngati gifted her chosen people with dominion over her dark and turbulent kingdom. (watershaping)
 * Our origin, our destination, our home. Wherever we go, she is the horizon. (Ukaizo)
 * The emerging image is not exactly a map, but an index of islands and coordinates organized in relation to each other. You recognize several of the cited locations as containing nothing but open water. Charting a path by this obsolete system would be impossible now. The word 'Ukaizo' stands out from the other named islands. By choosing the option to take a rubbing, you gain the Huana Chart, which will be instrumental in finding Ukaizo. If you destroy the disc and tell Prince Aruihi, you will suffer a Major reputation loss with the Huana.  There appears to be no reason to destroy the disc; it seems that other factions make no use of it later.


 * Turn in the quest
 * When you leave Motare o Kōzi, you will be pursued at sea by Captain Pai of the Royal Deadfire Company, who wants the Huana Map for the Rauatai Empire. If he catches you, and you have Good 2 reputation with the RDC, he'll acknowledge you as a peer and will leave you alone. Look for him before you sail; with a fast ship you can slip past and outrun him instead of having a confrontation. Once you get back to Neketaka and turn in the quest to the prince, you will not be bothered by Captain Pai again.
 * Return to Prince Aruihi for your reward. You can diplomatically ask for more cash, getting on top of the payout if you have at least Good 2 reputation with the Huana.
 * Plan to return to Motare o Kozi if you still need to save Baltia.

Loot

 * Nerian's Ward: Found within the Rotten Lady's / Green Lady's tree.
 * Wooden Spider Figurine: Wooden chest to the northwest of that tree.
 * Lil' Babs: Needs rescuing in the southwest.
 * Rotward Amulets: One or more scattered across the grove.
