can i keep this githyanki, mom?

[rossik]

(im playing some hibrid of 2ed and 1ed)

githyanki have plane shift at will, right?
could anyone think of a reason to why and how would one of them (A 5 level fighter githyanki-i need his +1 two hand sword) be traped inside a room of a tower?

if "by magic", could you think of one and why?

what does cutting the silver cord does to him?

(oh, btw, first time in the new look forum! very nice, congrats!)

Don't know if it was ever a rule, but a common way of warding an area off from plane shifting was enclose it in something living. A prison covered in vines or walls covered in mould for example.

Alternatively, rule that certain metals (such as lead) are impenetrable, then stick lead panelling on the walls.

I think that would instantly kill him, but I could be wrong.

Keep him unconscious permanently? That would stop him from plane shifting

I don't know about 1e/2e but in 3.x, it would but the githyanki needed a silversword to sever the silver cord.
