The runes they inscribe on their weapons are their mana pool (of a sort). As they use their abilities, the runes will be exhausted. After a period of time the runes will refresh. So, they don't have a traditional type of mana pool. You'll most likely see some screenshots of it, but the Death Knight (at current) has three different types of runes that they can inscribe on their weapon: Blood, Frost, and Unholy. Runes can only be inscribed out of combat ( all of this is subject to change as development continues.)

The rune types don't dictate a new damage type, they're simply a resource that spells and abilities will use when you activate them. The spells and abilities won't necessarily be “blood, unholy, or frost” damage.

Imagine it being three different energy pools which you can change the size of before you get into combat.
