The whole wing had been abandoned just because whatever it was was so very dangerous - that guaranteed he'd insist on going. It wasn't, of course, before I got there. I made a number of very fine nets, almost like cobweb, and decorated them with little hooks and a sort of distillation of formic acid. So as he crashed around through the 'webs' he got cut and stung while finding nothing. And for a bonus, I believe at least one of his friends suffered alongside him." Had it been Fandral or Hogun? Likely not Volstagg; he'd been slightly older and calmer.
