I shall open a portal to take you back to the druid that brought you here. You and your crusader have my well wishes. I hope that this acorn is able to purify your crusader and save him from the wretched fate of the plague.
Well met, <class>. I knew that you would return, despite my warnings, but I'm pleased that you heeded my desire to not risk anyone else.
Why have you come back to me?
Tirion sent you to Remulos? I'm... I'm flattered. One does not call favors in with beings of such power idley, no matter how noble or altruistic they might be. You are too kind to have gone to such lengths on my behalf. You have my thanks.
Plant the seed - I am ready.
Before you leave, if you have something to do near Moonglade, now would be a good time to do it. You can then taxi back to Moonglade and use your free teleport. Once you accept, you can ask to have your Moonglade Return Portal spawned in, which will do so to Remulos's right:
I wish to return to Arch Druid Lilliandra. Can you send me back to her?
This quest can be used by Druids to make their into a "Teleport: Alliance Vanguard", if they chose not to complete it.
