Tarot Dungeon Poem

Sadko told the Byzantine Envoys this poem before sending them into the Tarot Dungeon:

    There were two tunnels and one died.
    One has secrets deep inside.
    In the other: dog-like men
    Plot and bark and plot again.
    There were two tunnels and one died.
    Now they lie here side by side--
    One is dead and one asleep.
    May they both their secrets keep!
