Choose one of the unexplored spaces next to a hex where
you have a Ship or an Influence Disc and turn a hex tile
from the corresponding stack (I, II or III) in it. If you Explore
from a hex with only a Ship, it must not be "pinned" (see
Move on page 14)...
• the hex can be placed only to the spot that you explored
• the hex must be oriented so that at least one of the
Wormholes on the hex connects with a Wormhole on
one of the hexes where you have a disc or a Ship
So in other-words you pick the spot that you are exploring but can orient the new hex in any way you want to as long as that is a legal placement. (wormhole connected) So if your "spot" is adjacent to 2 or more hex's you can chose which one to connect it to after you draw the new hex tile.
