This is my first monster that I've created for 4e. It is the first monster listed in the 1e Monster Manual and I've added it to my list of 1e Monster Manual monsters for 4e. You might notice that I've added Frequency, Environment, No. Appearing, % In Lair, and Treasure Type. This is because I'm putting together my own house rule Monster Manual with the intent of playing 4e D&D in the old school fashion.
For reference, I used the descriptions of the aerial servant from the 1e MM p. 6 and the 3.5e Tome of Horrors p. 9. If you are familiar with the AD&D aerial servant, you'll know that it can be summoned by a PC cleric. In 4e terms, this obviously requires some sort of ritual spell. Unfortunately, I have not defined such a ritual here.
Frequency: Very rare
Environment: The Elemental Chaos
Number Appearing: 1
% In Lair: 0
Treasure Type: Nil
The aerial servant is a semi-intelligent form of an air elemental. It is typically encountered only due to summoning.

An aerial servant can release a blast of wind. Ranged 8/16; +21 vs. AC; 4d10+7.
This ability is constant, allowing an aerial servant to remain invisible even when attacking. This ability is inherent. This ability does not function when an aerial servant is on the Astral Plane or Ethereal Plane, but instead grants the creature lightly obscured concealment.
When summoned, an aerial servant creates a mental link between itself and the caster who summoned it. Should the aerial servant fail the mission it has been assigned, it returns to the caster and attacks him. The aerial servant can find the caster as long as they both are on the same plane of existence. If the caster leaves the plane, the link is temporarily broken. Once the caster returns or the aerial servant enters the plane the caster is on, the link is immediately reestablished and the aerial servant moves at full speed toward the caster's current location. Only when the aerial servant or caster is destroyed, is the link permanently broken.

AERIAL SERVANT TACTICS
Aerial servants attack by using a shearing blast of wind as a weapon or by grabbing an opponent and crushing it within their powerful grasp. Aerial servants can only be killed on their native plane. If slain elsewhere, they simply dissolve into wisps of vapor and return to their home plane. An aerial servant's natural weapons are treated as magic weapons for the purpose of overcoming damage reduction.
AERIAL SERVANT LORE
A character knows the following information with a successful check.
Arcana DC 10: Aerial servants are semi-intelligent creatures from the Elemental Chaoes that often roam the Astral Sea. They normally are only found on this world as a result of some sort of summoning ritual and commanded to perform some task, often being required to use their immense strength to carry objects or aid the summoner.
Arcana DC 15: Aerial servants can carry weights in excess of 400 pounds.
Arcana DC 20: If the aerial servant is frustrated from completion of its assigned mission it becomes insane, returns to the spellcaster which sent it forth.
[Disclaimer: I'm relatively new to making 4e monsters. Although I'm pretty sure I did a good job, I may have missed a few details. If you think there needs to be changes, let me know.]
