Key from Demon

[esteban]

I need the key for the mechanical door in the elven lands
The Demon keymaster just says he's busy - no other option
If this is where the key is how do I get it?

[Stever717]

you have to defeat the mistress of the castle first.

also since that part of the main quest you may need to wake the elf queen before you can go in there.

[esteban]

I've done that

do I need to leave the area and return - or wait a period of time.

she says she's my servant etc etc..............

but he gives the same reply each time I click on him

[Stever717]

Have you waken the elf queen yet?

[esteban]

Hi

I don't think so - just checked my completed quests

Where do I find that quest?

Thanks

Steve
