Let me explain the entire game step by step:
111, preparing to break through the block. An obvious move. Waiting for birds from 112.
112, breaking through the air units, and obviously the gargoyles, as they are blocking a part of the spawn, I see a consul, a stable, and a dwelling.

Is this a block? Where is the block? Where does the confidence come from that gargoyles are blocking part of the spawn? :confused: As can be seen from Sauron's scouting, the path leads upwards. The fact that Brissa opened the way also suggests that the entire spawn is above. The direction Gretchen aimed could have immediately ended in a dead end after 2 steps. As the exploration shows, most of the spawn is above the castle, but there is nothing there, while there is something below.
