Nephelia

The "slave elf" of the title. An albino ostracized by her fellow elves, she refused to protect them when slavers attacked their village. She was being delivered to the mage Marchosias when he died unexpectedly, so she was then auctioned off to Zagan.

The moment she came into Zagan's possession, the first words that came out of her mouth were questioning how he was going to kill her, and suggesting various methods to carry it out. Zagain is properly horrified and has to constantly tell her he has no such intention.Her Celestial mysticism means is that every part of nature in the vicinity tries to kill whatever poor bastard the sorcerer wants it too. Including inanimate vines. And baby animals. They're all locked into a vicious, merciless Hive Mind.After Zagan comes to her rescue at the end of Volume 1, she presents her Slave Collar and asks him to put it back on, declaring herself to be his possession for life. He happily accepts.

She is a very good cook, usually making the meals both she and Zagan eat.She is clearly the main reason Zagan has become a better person.
