The game Summoners is a tabletop skirmish game for two or more players. Each player assumes control of a powerful sorcerer, with whom he travels the shattered shards of Kalundra. During a game these sorcerers can summon many different creatures to support them, yet to do this they need magical energy, which is hidden everywhere on the battlefield in the form of of magical fragments of the great Crystal. No sorcerer is able to work magic or open portals without these mana-gems, wherefore hostile sorcerers fight bitterly over this vital resource. Only those who make optimal use of the abilities of their creatures and keep an eye on their energy reserves can leave the arena as victors. —description from the publisher (translated)
