Agenda 1a deals 1horror when an encounter card effect makes you move. Do i get 1 horror when my extradimensional location gets discarded and i am moved back to the starting location? It is the starting location that forces the move.

The designer answered:

"Yup! You are moving from an encounter card effect (specifically, the forced effect on Another Dimension), so the forced effect on the agenda will trigger to deal you 1 horror. "

Does it imply that Another Dimension is an encounter card? Is it in the rule book that locations are encounter cards?

Thanks

Encounter cards = Scenario cards, and include locations, treacheries, enemies, acts, agendas, and scenario reference cards.
