Arden Sylvain's Links
Arden looks up to Vance. He's legendary to the point that Arden made his magical focus a dagger to be more like his hero.
Vance hasn't met Arden, but if he had he'd probably tell Arden that his magic is cute, but he needs to be careful before he gets himself killed.
Arden permanently fused with Vance in a freak magical accident, so he doesn't like Varian at first, but learns to accept his situation as a conversation in harmony rather than two separate entities. If he met Varian he'd be uncomfortable with how similar and different they are.
Arden is one of Varian's components. He talks about Arden like he's a little kid with much to learn and he is, but also respects that Arden tries his best and is generally as heroic as he can be.
