Skink-in-Tree's-Shade Quests, (Sadrith Mora Mage's Guild)

Escort Tenyeminwe - Escort a scholar to the town's docks.
Skink in the Sadrith Mora Guild Hall will offer you his first quest once you've completed Edwinna's Detect Creature Potion quest. Stink asks you to escort the scholar Tenyeminwe from the Muriel's Cornerclub to Gals Arethi's ship. The Cornerclub is just across the bridge from the fort, and the docks are just to the North West. Upon returning to Stink you are rewarded with an increase in disposition.

Arrange an Ashlander Meeting - Arrange a meeting with Skink and an Ashlander Wise Woman.
Skink in the Sadrith Mora Guild Hall asks you to arrange a meeting with a wise woman of one of the four Ashlander tribes: Urshilaku, Zainab, Erabenimsun, or the Ahemmusa. Skink doubts that the Erabenimsun will agree and suggests to start with the Ahemmusa. If you've gotten far in the main quest, you should know the location to all four camps (and they will be 
marked on your map). The Ahemmusa Camp is on the far North East corner of the island, North of Tel Vos (North West of Tel Mora). Sinnammu Mirpal, in the Wise Woman's Yurt in the Ahemmusa Camp, refuses to meet with Skink, but 
suggests her apprentice, Minabibi, who can be found in the Favel Tomb West of the camp past the Daedric ruins.
When you find Minabibi Assardarainat just inside the tomb, she agrees to meet with Skink but you must first kill the spirit of the tomb for her, the spirit of Kanit Ashurnisammis. Once you get rid of the spirit, Minabibi tells you to return to Sinnammu to get permission for her to meet with Skink. Do so, noting that no matter what you say to Sinnammu, she will let Minabibi go. When you return to the Sadrith Mora guild hall, Minabibi is already there waiting for you. Talk to Skink to finish the quest and receive the usual increase in disposition. Speak with Minabibi afterwards to receive an Ancestor's Ring (Summon Ancestral Ghost).

Telura the Necromancer - Take care of a former guild member that has turned to the dark art of Necromancy.
Skink in the Sadrith Mora Guild Hall asks you take care of a former guild member that has turned to using Necromancy, tarnishing the 'good name' of the guild. Telura Ulver can be found in Shal, North of Hla Oad on the West coast, just North of the Daedric ruin. Shal is a small cave with an assortment of undead before you reach the main chamber with Telura, who will attack you on sight. She's a powerful mage but once her spells are used up she's not too tough. Don't forget to check around for treasure. Returning to Skink you are rewarded the usual increase in disposition.

Ash Ghoul Soul - Capture the soul of an Ash Ghoul for Skink to study.
 If you've reached the rank of Wizard (7), Skink in the Sadrith Mora Guild Hall wants an Ash Ghoul soul for him to research. He gives you 2 Soul Capture scrolls and two Grand Soul gems for your task, and suggests checking in Yakin, a Sixth House cavern North West of Tel Aruhn, just West of Sadrith Mora on the mainland coast. The Ash Ghoul is a tough opponent that has a long nose and casts spells. Be sure you cast the Soul Trap spell in order to capture the soul, otherwise you might be searching a long while for another Ghoul to trap. Once the soul is trapped, return to Skink you are rewarded the 
usual an increase in disposition. If you only use one Grand Soul gem, you get to keep the other.

Vampire Book - Find a very rare book of Galur Rithari about vampirism's cause and cure.
Skink in the Sadrith Mora Guild Hall asks you find a rare book for him, the Vampires of Vvardenfell . Apparently the first volume most rare booksellers should have, while the second volume is quite rare (of course, he wants the 
second volume). The only suggestion he gives you is to check the rare booksellers. You might also find out that the second volume is banned by the Temple, possibly the reason for its rarity. There are several places you can find a copy. One is in Jobasha's Rare Bookshop in Vivec, Foreign Quarter Lower Waistworks, for the low, low price of 400 gold (a large, dark red book). If you don't want to pay, you can also find one in the Hall of Justice secret Library, though the guards won't like you if they see you taking it. Yet another copy can be found in some vampire lairs (such as Galom Daeus). Whatever the method, when you return to Skink with the book you are rewarded with an increase in disposition and 1000 gold.
