A post about hags and underwater adventuring... and I didn't even start it (take that, CM)!
I recently posted a bit of this, over at
Phoenix Lore , to get some feedback on an ecology article I am working on.
The Hag-Touched: Oceanids, Harridans, Sea Hags, and Annis
(I reserve the right to publish this information and ideas derived from it elsewhere, as I see fit.)
In my campaigns, I accept Nigel Findley’s “Ecology of the Greenhag” (DRAGON #125) as canon. Simply stated, this means that the greenhag is the daughter of a night hag and an annis is the daughter of a greenhag. The article states that the greenhag is the offspring of a night hag and either human or demi-human father, while the annis is the daughter of a greenhag and either ogre or hill giant father. The offspring of an annis is always a female of the father’s race.
I have expanded upon that family tree, keeping the greenhag as the offspring of an advanced night hag known as a midnight hag and either human or high elf, while adding unique offspring from the union with aquatic, sylvan, and drow elves. I also added outsiders as viable fathers with night hags. Demons, devils, daemons, and demodands siring succubi, erinyes, naelle(1), and phlenar(1) respectively.
The greenhag, according to the article, can produce an annis through her union with either an ogre or hill giant. To this I added the sea hag as a daughter from either a merrow (aquatic ogre) or bog giant father. I rounded out the roster with new ogres for jungle, desert, and arctic environments, while choosing from large-sized giants from similar locales, to sire unique hags for these settings. To this I added a union with trolls, to account for the hags in Frostburn and Sandstorm, as well as the bog hag in Oriental Adventures. This left the scrag, as father to the shoal hag(1) and the jungle troll as father to an as yet unnamed rainforest-themed hag. If I was to borrow hags from either Unapproachable East or 4e, I could make the shrieking/howling hags daughters of jungle trolls, and death hags daughters of jungle ogres.
Thus one begins with the night hag as the progenitor. The greenhag, salt hag(1), woodhag(1), and greyhag(1) follow as half-hags (a template), as outsider’s blood sullies the acquisition of this particular template. Third generation hags, or hag-touched (a level adjustment) creatures include the annis, bog hag, dune hag, marzanna, harridan(1), shrieking hag, death hag, and oceanid(1).
Greenhags that spend the majority of their time in the water are known as shellycoats, and differ in appearance and abilities from greenhags, in a similar manner as aquatic storm giants differ from their cloud-dwelling kin. Hag-touched offspring of shellycoats include the sea hag and shoal hag(1).
A fourth generation of hags, the hag-cast, include hags created in unconventional means such as the elemental hags born of a night hag’s ashes, the parthenogenetic reef hag(1), and the stormfire hag(1). In addition, hag-blooded beings have been known to appear, several generations after their hag-touched ancestors.
In addition, midnight hags have been known to assume a male gender and sire offspring with human, derro, and demon (yochlol) mothers. Unions between gender-changed midnight hags and unchanged midnight hags are not unheard of, though the offspring is almost always a night hag. Any male child born of such a union is quickly slain and consumed.
A gathering of three epic hags, including the likes of the midnight hag, is known as a covyn, while gatherings of three lesser hags such as half-hags, hag-touched, hag-blooded, and hag-cast is known as a clutch. A clutch is often sponsored by a more powerful hag.
Midnight Hags have been known to train other hags in the ways of the beldamei; a prestige class exclusive to hags. Another hag-oriented prestige class, reserved for those embracing darker magics, includes the body snatcher. Both of these paths begin with the onset of demon fever instilled by either the bite of a midnight hag or that of her improved homunculus.
In such a way a hag-touched (Level Adjustment) oceanid could be a beldamei (Prestige Class) member of a clutch (Organization/Affiliation).
That might give you a thing or two to think about.
