Summon
From Guild Wars Wiki
Summon is a term frequently used to describe NPCs that are created through the use of summoning stones.
However, it is also a collective term used to refer to all NPCs that a player can create through various methods to aid them in explorable areas. These methods include the use of various skills, such as necromancer animate spells which raise minions from corpses, ritualist skills that call forth spirits from the Mists, as well as certain PvE-only skills, such as those found within the Asuran skill line.
