You can return to castle directly only if you teleport to 0F/N0/E0.
Your party will appear into moat if you teleport to another coordinate of 0F.
Then your party's bodies will be carried to temple. Don't worry.
One of the most safely choice is up to 5 levels to B1F, because there's no stones and monsters are too weak.
WARNING: NEVER RESET THE GAME IF YOU SEE THE MESSAGE "DROWNED" OR "IN THE AIR". If you reset the game by pushing home button, the party will be missing forever!!
> I remembered I needed to invoke the amulet....so I teleported up 6 levels to the castle, and drowned.??I guess they are all dead now.

> So much for that!??they are all gone now....
