The Grey Tower

Grey Ajah Weaves (Set)
Lazy scribe:
Weave three thin flows of Air and an even thinner flow of Spirit around a pen or quill, whichever is available. The quill will write as the weaver dictates, but will still need to be dipped in ink as it runs out. Unless the weave is removed, the quill will not write while a hand is touching it, so keep hold of it unless you want interruptions recorded!
Focus of empathy
A web of Spirit, and an identical one of Air, laid precisely over an object, will give off a low, colored glow, visible only to the one who forms the weave. The color will indicate the level of anxiety or emotion felt by a person holding or wearing it. Perfect for sneakily placing on a ring or brooch worn by someone adept at giving nothing away. Often used by newer Greys, those well versed in Daes Dae'mar would have little need.
OOC: Think of the mood rings you can win in arcades that go by the heat of your hand, but accurate! White = utter calm, red = passion and so on.

Chameleon Tendencies:
Pull out strong threads of Air, and lace them around strands of Fire. Then use alternate thin and thick flows of Water to pull the weave together and wrap it around yourself. Non-channelers will find their eyes slide past you as long as you remain still and silent, unless they concentrate hard on you. This weave leaves all but the most observant believing they simply have not noticed you, avoiding the attention caused by removing an Invisibility weave and appearing in mid-air.
Adapted from Leanna Sedai's Invisibility Weave from the Advanced One Power Class.

Reinforced Documents:
Thickly weaving threads on spirit, earth and water into a pattern within a document, and tying it off in a special way(A thick border of all three threads), helps keep a document from casual wear and tear. Also makes it much harder to catch on fire.
Variation on Reinforced Documents:
By altering the flows of water and adding a touch of fire, a thin thread woven last and interlaced between the other flows, the document can be protected from fire and water.
Quick Sand:
May be used to spring a trap, but has been used to hide another object inside the platform he was on. Good for hiding documents during a Siege if you do not have arms to carry the document. (j/k)
Description: Weave Water and Earth together and send it into the ground until it is similar to quick sand.

Encryption
This must be woven very precisely
Channel Air, Spirit and Water in equal measure, forming the flows of Spirit and Air into a finely meshed net.
Weave the flow of Water through the gaps and hold the flows.
Channel another, finer, thread of Spirit and thread it in and out of the net.
Keep careful track of this thread, as it decides which variation of the weave it will become. This should not be more than five or six loops until the channeler is familiar with the weave.
Tie off the flows and place the weave on a document.
Immediately the letters will scramble, jumbling into a nonsensical sequence.
By placing the last thread of Spirit differently, the letters will rearrange into a different order. It is possible to make a written key, but impractical given the number of variations.

To decipher the code, lie the same weave over the document, but with the last flow of Spirit reversed, i.e. last loop first and so on. Only whoever wove the encryption weave will know how to place this thread. If they fail to remember the weave correctly, or someone else tries to guess, the document will burst into flame without warning.

Suggestion
Fine flows of all five elements must be channeled, a web of Spirit overlain with a web of Air, twisted around each other and overlain in turn with a web of Water. Touches of Fire and Earth must be interlaced through the weave, and more threads of Spirit. These last should be left trailing out of the weave until it has been placed on the subject. Momentary confusion will take hold as soon as the weave is laid, and then the remaining threads of Spirit should be allowed to fall into place. The weave will look like the most intricate of laces.
The subject will be more open to whatever the weaver says, but only for a short time and will still require measures of persuasion.

I also went back and corrected some grammatical and spelling errors on the secret weaves
