He helps to advise Adar on decision making and ruling he often has cooler headed sight on matters Adar does not, and he despises Waldreg. I think early on Waldreg would make some bad remarks to him & Nîrndîr just finds him a bootlicking bumbling fool.

One of he and Adars main bonding points is hair & self maintenance, there are occasional days where they slip off and he helps Adar wash & untangle his hair, bath together, and he also helps clean wounds when they arise. It does takes some convincing to get Adar to leave.
