殳: pushing through

殳:  a lance.  Wha--?  Well, the bottom is a hand, and the top is a lance after you've smushed it into a wall so it's all curved.  Best I can do here.

Now, for the descendants.
殳, lance/pike:      First, there was a pike(man).
穀, grain/cereal:    Like many adventurers, he started on a farm.  He poked grains into the earth with his lance, to get a crop of rice.
殻, husk/nutshell: Didn't work, so he poked in the earth with his lance and found nut shells.
般, carrier*:          He tried getting a job on a carrier ship, but...

没, drown:            He fell into the water and nearly drowned.

役, role/military service:  Finally, seeking his fortune, he came to a crossroads.  They drafted him for the role of military service.
殴, assault:           The pikemen made an assault on the city ward.
撃, shoot at/aggression: The army used their hands to shoot lances in their attack.  (車 here is used as army.)
疫, epidemic:        There was an epidemic, so he used his lance (to enforce quarantine?)
殿, mansion:         Finally the pikeman came to a mansion.
段, stair:               He made his way up a staircase.
鍛, forge:              He found a forge at the top.  There at the forge was his opposite number, with a fresh-forged lance.
投, throw:             They threw their lances.
股, thigh/crotch:   Like the Fisher-King in Arthurian legend, he got a wound to his thigh or crotch, from a lance.
設, establish:        Ultimately, to establish anything, he found you need words not weapons.

This doesn't fit, so I'll put it by its lonesome:
殺, kill:                On the cross, or poetically a tree, they killed Christ; the soldier stuck a lance in his side.

* There are more with 般 in them, but the list is getting long and I put these with 舟 (ship) anyway.
