I got a name suggestion. "Alliance of the Savage Wilds" or "Grrrrrrrrrrr"
I thought about this a bit, and I'm not sure they fit the faction that well. I certainly appreciate the suggestions!

I'm leaning towards something like Beastmen of the North. Also there's a chance I could just ditch the Beastmen theme, make them humans, and go for the Viking theme. The problem with a Viking theme is Vikings were good at archery, while I don't want this faction to have ranged fire.
By the way, I think I've come up with some interesting spells for the Druids. Note the normal Druids will have about 100 points of spells on top of a ~167 point body, and the Elder Druids will have about 200-250 points of spells on a 250-300 point body. I'm also pretty sure they will be the only units in this faction without the Savage Fury ability.
Loxodon Druid Spells: (These are ~267 point units with a horrendous attack and decent defense)Infuse: Cast during your Movement and Command phase, after all Final Rushes are made. Mark up to three Blood Magic boxes on your units.
Ritual of Speed: Cast during your Movement and Command phase, after all Final Rushes are made. Deal 1 damage to up to three of your units (this damage does not cause rout checks). Those units gain +2 MC and cannot Final Rush this turn.
Invest Avatar of Anger: Cast at the beginning of your Movement and Command phase. Spend two Command Actions, and the caster cannot move this turn. Choose a unit you control with the Savage Fury ability. That unit gains the Avatar of Anger effect, and change its Standing Order to an unmodified "Close". If this would cause you to control more units with the Avatar of Anger effect than Loxodon Druids, remove the Avatar of Anger effect from one or more of your units until this is no longer the case (those units do not make a rout check).
After your units have been deployed but before assigning standing orders, you may choose a unit you control with the Savage Fury ability for each Loxodon Druid you control. Those units gains the Avatar of Anger effect.
Avatar of Anger:A unit with the Avatar of Anger effect gains A(+0) +1/+1, D -1/-1, +1 MC, Large, Fearsome, and passes all Courage checks. It always has the "Close" Standing Order and may not be given a Standing Order Modifier or be directly controlled. Reduce the unit's Blood Demand by 2 (to a minimum of 1).
Only one unit per Loxodon Druid you control may have the Avatar of Anger effect. If you control fewer Loxodon Druids than units with Avatar of Anger, you must immediately remove the Avatar of Anger effect from one or more units until this is no longer the case. Units who lose the Avatar of Anger effect in this way must make a rout check in the next Courage phase (unless this was caused by the Invest Avatar of Anger spell).
Loxodon Elder Druid Spells: (These are 500+ point units with an awful attack and pretty good defense)Greater Infuse: Cast during your Movement and Command phase, after all Final Rushes are made. Mark up to four Blood Magic boxes on your units.
Ritual of Speed: Cast during your Movement and Command phase, after all Final Rushes are made. Deal 1 damage to up to three of your units (this damage does not cause rout checks). Those units gain +2 MC and cannot Final Rush this turn.
Entangling Vines: Cast during your Movement and Command phase, after all Final Rushes are made. This spell deals 1 damage to the caster (this damage does not cause rout checks). An enemy unit of your choice gains -1 MC and A(-2) -0/-0 during its controller's next turn.
Invest Avatar of Wrath: Cast at the beginning of your Movement and Command phase. Spend two Command Actions, and the caster cannot move this turn. Choose a unit you control with the Savage Fury ability. That unit gains the Avatar of Wrath effect, and change its Standing Order to an unmodified "Close". If this would cause you to control more units with the Avatar of Anger effect than Elder Loxodon Druids, remove the Avatar of Wrath effect from one or more of your units until this is no longer the case (those units do not make a rout check).
After your units have been deployed but before assigning standing orders, you may choose a unit you control with the Savage Fury ability for each Loxodon Elder Druid you control. Those units gains the Avatar of Wrath effect.
Avatar of Wrath:A unit with the Avatar of Wrath effect gains A(+2) +1/+1, D -1/-1, +1 MC, Large, Terrifying, and passes all Courage checks. It always has the "Close" Standing Order and may not be given a Standing Order Modifier or be directly controlled. Reduce the unit's Blood Demand by 2 (to a minimum of 1).
Only one unit per Loxodon Elder Druid you control may have the Avatar of Wrath effect. If you control fewer Loxodon Elder Druids than units with Avatar of Wrath, you must immediately remove the Avatar of Wrath effect from one or more units until this is no longer the case. Units who lose the Avatar of Wrath effect in this way must make a rout check in the next Courage phase (unless this was caused by the Invest Avatar of Wrath spell).
EDITS: Adjusted basically all the spells and Avatars :p.
