We are very much looking forward to hearing and discussion the prospects of LSST in a vastly evolving and exciting field. We especially also welcome all our junior people (explicitly including summer students!) to join this discussion. KEG is a format of open discussions around forthcoming science cases with a next generation observational facility. This will be a great opportunity to learn and follow a discussion on what the science cases in the next 10+ years with faint galaxies around our Milky Way and neighboring galaxies are.
