Caenemung

The Caenemung is a species of hostile, giant, marine creatures of which there's currently only a single specimen known, residing in the Sejan beach cave. A fight with it can be triggered when offering help for Breirb, since it's been annoying the colony mostly by stealing fish. Physically, it is a huge, dark serpentine without limbs. Its head, adorned with coral-like horns or antlers, has no eyes, allowing for strong headbutts that complement bites with its teeth.

In combat, it is recommended to bring strong equipment and to be careful with attacks. Due to its resistances, weaker effects might not even have an effect on the creature. This combined with its hitpoints and strong attacks (notably a Massive tackle) makes for a challenging fight. If the player loses, however, they can return to the cave at any time, with both combatants' health restored. If the player wins, the Caenemung retreats and escapes into the sea, never to return.

Beach comeback
After defeating the Caenemung, it can be randomly encountered on beaches around Sejan. It lunges from the sea and attacks the player. The player has several options and outcomes (possibly fatal):
 * Run away (Agility 6)
 * If successful, the encounter ends.
 * If failed, attempt to dodge the creature (Agility 8, nonsensically)
 * If successful, the encounter ends.
 * If failed, the player dies.
 * If failed, attempt to punch the creature (Strength 8)
 * If successful, engage it in combat
 * If failed, the player dies.
 * Attack it
 * If player wins, see below.
 * If player loses, attempt to roll away from the creature (Agility 8)
 * If successful, the encounter ends.
 * If failed, the player dies.

If the player runs away, they can be attacked at any point on the beach again. In most cases, if they win, the same also happens - they can attempt to grab its tail and prevent it from escaping, but that turns out to be unsuccessful.

If the player however has a roll of rope on them and they pass the checks of Agility 8 and Strength 10, they can quickly tie a lasso and catch the creature before pulling it to the shore. The player can then examine the Caenemung and figure out that it's a female. Male players can then have sex with her. The creature has three orifices and if the player chooses to penetrate the middle one, there's a 33% chance at impregnating her.

On the next visit, the Caenemung doesn't attack the player anymore and instead seems to be affectionate towards him. Due to how she reacts to player's speech, it's probable that she understands him, though she's not able to talk. How this ties to the concept of The Understanding is unknown.

If she has been impregnated, she starts an encounter by stopping the player before thrashing her form on the beach, followed by her laying an egg, nodding in confirmation if the player asks if it is his. The player can either leave it and she takes the egg into the sea, never to return again, or he can kick it and destroy it. The Caenemung will then leave too, sorrowed, and doesn't return either.
