He grants Renarin the powers of the Truthwatchers, an order of the Knights Radiant which gives Renarin access to the Surges of Illumination and Progression. However, Renarin also has visions, which are also possible due to Glys' bond. This bond caused Renarin to hear screams when touching his killed Shardblade, which he initially believed to be a sign of his weakness or possibly insanity. Glys explained otherwise and told Renarin which order of Radiants he had joined.
Glys looks "...bright red, shimmering like the heat of a mirage. A crystalline structure, like a snowflake, though it dripped upward toward the ceiling." Regular Truthwatcher spren look different than Glys, like "the shimmer you see on a wall when you shine light through a crystal."  Glys looks different than regular Truthwatcher spren because Glys has been corrupted through contact with Sja-anat. 
It is unknown what type of spren (and therefore all other spren that Truthwatchers bond) Glys is. It is possible that he is a corrupted Reacher, or lightspren, however it seems far more likely that Reachers are actually the type of spren that form Nahel Bonds with Willshapers.
It is possible that Glys is a corrupted keenspren (mentioned by Wyndle in Edgedancer) 
- "Glys" is the spren's full name, rather than being a nickname like "Syl".
