A to Z Challenge, H is for Homard

Today will be another monster post.  Homard is french for Lobster and I'm of the opinion that Lobsters are an extremely underutilized in D&D's monster ecology.  Lobsters have giant claws, can escape quickly and most interestingly:

Longevity

(. . .) It has been argued that lobsters may exhibit negligible senescence and some scientists have claimed that they could effectively live indefinitely, barring injury, disease, capture, etc.[12] Their longevity allows them to reach impressive sizes. According to the Guinness World Records, the largest lobster was caught in Nova Scotia, Canada, and weighed 20.15 kilograms (44.4 lb).  --Wikipedia

Lobsters are immortal!  So without further ado I present the Homard, Lobster-men of the seven seas.  They terrorize shipping vessels of mercantile empires demanding tribute to their underwater immortals.  They wage war against any nation foolish enough to put their foundries waste into the waters edge.  Hommards grow larger and more wise with age, being the second longest lived sentient creature on the planet they have acquired a mass of knowledge that allows them to build sophisticated war machines and they have amassed spellcraft from the last age.  Their Nautilus ships can move freely beneath the waves and terrorize surface faring vessels, their fell magics can create whirlpools and towering waves.

The Nautilus is a giant smooth shelled ship composed of underwater materials and bound with ancient techniques.  It is larger than the surface dwellers dreadnaughts and nearly indestructible.  It is capable of moving through the seas completely underwater, destroying seafaring ship from underneath.  Many sea tales mention that the ship itself is alive but none have managed to verify the tale.  The Nautilus is however extremely vulnerable to elevated temperatures, should you be able to boil the seas you will be quite capable of handling a Nautilus.
