Once Xiang and Yang were definitively asleep, Kat started to ponder how to watch over everyone. Floating in place was fine sure, but it wasn't even midnight yet and Kat knew she'd have a bunch of time to kill waiting for everyone else to wake up. Part of her wanted to sleep to pass the time quickly but it this area was terribly unsafe. It just wasn't practical. Most of the wildlife here wasn't deadly for their bites or claws, but for the poison. Something that could be much more insidious.
So to pass the time Kat started to make an ice block raft to sit on. By pumping demonic energy into the water Kat could freeze it down to the mud… and then further still freezing even that. With a constant supply of demonic energy Kat was pretty sure the platform could be made quite stable.
