House provides both to them a simple hardened clay disk with house insignia on them by Aergrim and he tells them once their mission is complete they can break and shatter the disks to teleport back to house safely, as teleporting into the area is a one-way trip otherwise as there excists no physical roads to area anymore directly from Erelhei-Cinlu (so they use ancient trade portal to get there).
