>>279843498 (OP)Keep her well-secured. Elves are dexterous, they can squirm out of a lot.
Keep her magically sealed. Even ranger-type elves often have a little magic in them.
Donโt gag her. Elves say the darndest things when theyโre tied up, and theyโre fun to talk to.
And donโt rape her either. Itโs more fun that way.
