Before you set off, ask him about the details of the missions.
Once there, just mention the crates Cyrus is waiting for, to finish this quest.
As for collecting any new artefacts — mention that Cyrus will "rip your head off" if you do not get them.
The artefacts are an old golden crystal disk (Eldric will repair it in Chapter 2) and the ring of the staff fighter.
Now just return to the Monastery and give the artefacts to Cyrus. In return you will be able to choose between
- a small ruby,
- a ring of the staff fighter and
- a berserker scroll.
