Penumbra's Links
Tethered to Sanguine for the time being. Thinks that Sanguine is kind of a loser, but at least he's competent enough for Penumbra's purposes. It resents having to be under Sanguine's control most of the time, but it is always biding its time for when it can take more control back. Penumbra will protect Sanguine if he's in harm, for its own safety.
Tethered to Penumbra since the earliest he can remember. He thinks of Penumbra more as a rowdy dog than another sentient being. Since Penumbra can't (or won't) speak back to him, there's a big gap in their understanding of each other. Since it's so unknowable, he feels that Penumbra is kind of a ticking time bomb.
