Investigate the Blue Recluse

A disturbance has been reported at the Blue Recluse tavern in the Mage Quarter. Strange, invisible creatures now wander the tavern, and I fear a mana rift has formed there. I want you to investigate the tavern and capture those creatures. Use the cantation of manifestation in the tavern to make the creatures visible, subdue them then use a containment coffer to capture them. When you have enough, return to me with your filled coffers, your empty coffers and the cantation.
