@Personman: Sorry I didn't include Selia in the link! Melchia can still only manage two other recipients, and you hadn't posted in a while, so I decided to mix it up.
That said, telepathy happens at the speed of thought, so while it's up to the DM, we probably aren't standing around silent for too long; a great deal of information can theoretically be transmitted in a smaller amount of time.
Melchia speaks aloud to the strange voice.
"...So you want us to rouse the unconscious one? He is our prisoner, a failed assassin. He's also a cultist, a servant of dark powers known only as the Deep. Does that mean anything to you?"
He shoots Selia a meaningful look, and she can feel a link establish to his mind.
<That took the last of my power. If we must reach some manner of consensus, best we all have access to private communication. Apologies for not including you in the link earlier; my powers are still limited with regards to simultaneous linkage. The mindlink should last about twenty minutes, though I doubt this entity has that kind of patience.>
