Zerith-var is one of two Khajiit player companions from The Elder Scrolls Online, a massively multiplayer online role-playing game set in the world of The Elder Scrolls, developed by ZeniMax Online Studios and published by Bethesda Softworks.

Zerith-var is an ancient Khajiit Necromancer, brought back to life by the Daedric Prince of Dawn and Dusk, Azura. During his quests, the player assists him in defeating the Rajaska: corrupted Khajiiti moon-singers (also known as Twilight Cantors) that curse other Khajiit to "fall to the Bent Dance" and become dro-M'athra (Khajiit possessed by Namira, the Daedric Prince of Hunger and Darkness). He is extremely kind, and has a soft spot for his cat, Ja'kh. He becomes extremely close to the player very quickly, frequently calling them "Tamiit," a Ta'agra (Khajiit language) phrase that roughly translates to "partner" or "of twin moons."
