1) You wouldn’t expect it from the name, or at least I wouldn’t, but Taste of Seaddle. That is, unless you want to spend a bunch of bits somewhere fancy.

2) Yes… I mean, every other Lyra’s last name is Heartstrings, so… But I have no evidence proving it’s mine…

3) Only Substance. I’ve watched a lot of the first and second, and some of the third and Revengeance (if that counts), but I’m not a huge Metal Gear fan. Not really a huge stealth fan, to be honest. Let’s just say the novelty of sneaking around wore off quite some time ago for me.

4) A spell that’s used to study spells. That does seem fitting for you. I guess the next step would be learning how to cast it?
