     Sentinels resemble large, floating eyeballs, with a protective armor. They were created by the arch-lich Mnemnosyne to patrol his island, watching all that happens. The Sentinels are capable of sending the images they see directly to Mnemnosyne. If they detect intruders, or some other problem, they will contact Mnemnosyne immediately, and Mnemnosyne will be able to see out of their eyes.
     Since their creation, others have learned the secret. Hence, Sentinels can be found guarding the homes and hoardes of any powerful creatures or beings.

Combat:     Sentinels are noncombatants, and have no combat values. If attacked, Sentinels will immediately broadcast a mental alarm, alerting all other Sentinels within a half mile radius (1d6 Sentinels) of the danger. The attacked Sentinel will remain at the scene until it has taken 10 hp of damage, and will then use it's innate dimensional door ability to flee to safety. The summoned Sentinels will show up in 1d4+3 rounds, and observe the attackers, reporting back to their creator.
     Each Sentinel, when harmed, will summon other Sentinels. Each additional summoning will call 1d6 other Sentinels, -1 for each previous summoning. For instance, if a two Sentinels summon others, the third will be able to summon 1d6-2 other Sentinels. If it rolls a 2 or less, no other Sentinels are within range of the summoning. As soon as a result of 0 or less is obtained, there are no other Sentinels in the area, and no more can be summoned.
