From the official post:

Hello and welcome to the first Foundry Challenge!  These challenges will be posted every 4 weeks, which includes 3 weeks to make your mission, and 1 week for the community to play through all of the missions and cast one [1] official vote for a winner. At the end of the 1 week of playthrough and voting, a winner, based on a simple majority of votes, will be announced and awarded 500 STO Promo Points for the C-Store.

Today we start the four-week run of the first Foundry Challenge: Conundrum on Risa

While on shore leave on Risa, the murder of a Stahlonian diplomat takes place on the island you are visiting. This diplomat was recently involved in talks with the Federation and KDF to join forces in combating the Borg advancement in the Alpha Quadrant. The loss of this diplomat is a tradgedy, and will cause a step back in negotiations, as the Stahlonian government was already worried about getting involved.

As the most senior ranking officer on the island at the time of incident, you have been tasked with investigating the events that lead up to the murder, including finding the culprit. As you begin questioning the locals, you stumble across clues that seem to follow some sort of pattern. As the investigation continues, you begin to realize there seems to be a riddle of sorts involved.
