Megeleus

He swears, if Elwy jumps out and spooks him from her stupid sap holes, he's going to die! Then come back and haunt her.

Whenever he's not constantly eyeing her sap nests warily, wondering which one she's squirreled into, he's playing games with his other sister, Kona. The clan recently got a full chess set together, so he loves playing it against her. At least, when they can pry out of the clan leader Selriona's claws. Maybe one day he'll challenge her for it!
Kona and Elwy are usually out doing their own things. That leaves Megeleus to stay at home in the lair, tending to his duties. For a while he wasn't sure what he wanted to do with himself - playing chess wasn't exactly a 'duty', though he still gets together with Kona for a round or two - so he had to find something.

As time passed, though, the smell of spices and savory bugs drew him to Lisse's corner of the caverns. That, as they say, was that. Now he hangs out around the mirror's kitchen, helping her cook the clans' nightly feasts. She's not very talkative though, in typical mirror fashion, but they can still get good work done and he feels she likes his company. That makes his fins flutter; he likes her company too.
