The Sentinels formed in the aftermath of the the Silver Storm. Most of the heroes operated in Emerald City for only a short time before the Storm, but it brought them together. One of the Sentinels, Wyrmhole, is a stormer herself and although confused when the Storm occurred, nonetheless helped some of the future Sentinels stop the newly-created stormers as they rampaged through the city. The group originally formed under the leadership of Sophie Anderson, a supergenius multi-millionaire paraplegic white-hat hacker who worked under the Codename "Bonnet Blanc" and were named the Emerald City Knights. The team comprised of the teleporting Wyrmhole, the android Valkyria, the wind-controlling Turbine and later the construct-creator The Cartoonist and the alien Xeno but in time effectively disbanded as a formal group when several of their number left Emerald City for personal reasons. The remaining ECK members (including Sophie Anderson) continued working together in a less-official capacity.
The actions of the ECK team, and the events of the Silver Storm, got the attention of Maximillian Mars of MarsTech. Realising that there was a need for superheroes to defend Emerald City, Max Mars put the financial and scientific power of MarsTech backing behind Sophie Anderson, officially employing her as a MarsTech Lead Researcher whilst backing her research and the formation of a new group, which would in time be called The Sentinels. Although initially The Sentinels were an extention of the remains of ECK, ie an unofficial group of superheroes working together in various degrees of official capacity, slowly some of the pre-Storm superheroes and new stormers worked together and helped the authorities investigate the cause of the Storm. This led them on a series of adventures culminating the creation of a formal team and saving Emerald City from the alien robot Tellax. Whilst a number of the Sentinels knew each other at least somewhat before they teamed up (during the ECK period or otherwise), none of them had worked together more than a few times before the official formation of the team.
Now, some months later, the Sentinels have cemented their role as heroes in Emerald City and are well known. Individual members are more or less accepted by the populace and the authorities. Mongrel, due to his appearance, and Xeno, due to her alien nature, have the most difficult time in that regard, but most of the others are quite popular.
