# Forgejo #132: the voice of the quest chain.
#
# GameState walks the chain and QUEUES what it wants said (see
# GameState.quest_messages); this node is the thing that says it. The split
# is not ceremony: quests advance in the autoload, which keeps running on a
# planet surface where there is no narration banner at all, so a line
# emitted straight at a banner would simply be lost down there. Queued and
# drained, a quest finished on a surface is read out on the way back up.
#
# Draining every waiting line at once is safe: the banner queues lines
# itself and shows them one at a time, and each one stops the game until it
# is acknowledged (#128).
