Drowning Seas - only playable on a company taking next M/H phase?

[Konrad Klar]

Environment. Playable on a company that moved this turn to a site with a Coastal Sea [ ] in its site path. Target company loses one item of its choice and its player must randomly discard two cards from his hand.

Alternatively, if Doors of Night is in play, target company must immediately return to its site of origin.

If a company is moving to a site with a Coastal Sea [ in its site path and this is the first M/H phase of the company, then the company is not a company that moved to a such site this turn.

Conversely, the company that moved from Endhellond to Grey Havens, its player played Bridge and now the company is moving from Grey Havens to Rivendell is a company that moved this turn to a site with a Coastal Sea [ ] in its site path.
