The subject of this article or section is part of Hallow's End, a seasonal event that lasts two weeks. Once the event has run its course, this will no longer be available until next year, but there are no guarantees.
You must get there in time to intercept the exchange and retrieve the crate before Xylem gets his hands on it. If you can get the crate, meet me at the Wyvern's Tail[76, 49.2]
Tendrils of dark power dance around the crate, but there's no trace of Sanath Lim-yo. You can now claim the crate and return it to your employer.
Dialogue
Upon entering the area with Sanath and Maxim, Sanath says the following:
Archmage Xylem does not bargain with the likes of you, ruffian. There shall be no payment! What's this, an intruder? Let's see what the artifacts inside this box can do, shall we? This isn't supposed to happen!
Sanath disappears just as the Unleashed Voids materialize.
Notes
Find the burning wickerman in the courtyard. Behind it is a flight of steps that lead through a shattered entrance. By now you should notice the trail of spiders you saw earlier. Follow them around the corner and you will find Sanath killing Maxim.
The Unleashed Voids that Sanath inadvertently lets loose from the crate are level-specific.
If you find you cannot interact with the crate, try walking back through the archway and then re-approaching Sanath. The dialogue and scene should unfold again.
