Blood of Dragons (spoilers RotE incl City of Dragons)

[Farseer]

These beings converted them to links. That should be enough. If it isnt, then these beings apologize.

Perfect, and a much better idea, thanks 'thul!

These beings do not like to burst your bubble, but its very, very unlikely that they are wizard-wood based. Aside from the Tarman, there is no wizardwood anywhere near the dragons. And the keepers respect dragons too much to take wizardwood away from them.

True, true. Oh! This has made me wonder about something that I really should have wondered about before. I think a little digging is required...
