Because Mythic Bastionland is so specific, I would hope it’s all quite obvious to anyone that has read or played.
That’s no criticism of your feedback here, but I’ll use this to explain to any others:
Knight and Seer: A knight (both PCs and NPCs) are knighted by a mystical seer. Both elements can be used separately in a game. There’s usually some tie but also some separation between the two.
The Tears is a Myth, a mystical feature/element in the realm. A myth traditionally consists of 6 Omens (1-6) that are uncovered throughout play, and generally build in grandeur and scope for that mythThey appear randomly and are loosely tied together (players are guessing what constitutes a myth/omen as they go). The players get to decide when they think a myth is resolved throughout play. These can appear anywhere (you can get forests in the middle of a desert as an example).
The game constains a lot of poems/poetic phrases as the intro to myths/knights. The two haikus in the images are those, evocative elements that a referee may use. In the one you described, the freedom can be both the eel and the fake seer, the boon - the frozen weapon. I decided to go with a haiku for its short, mysterious punchiness.
Essentially this is a Myth, that contains a site in the omens (the deep). The knight/seer is another flavour/character options that fit with the general theme of trials and water.
Essentially, all the elements are directly injectable into any Mythic Bastionland setting/game either individually or as a whole
