We present the results of our search for the faint galaxies near the end ofthe Reionisation Epoch. This has been done using very deep OSIRIS imagesobtained at the Gran Telescopio Canarias (GTC). Our observations focus aroundtwo close, massive Lyman Alpha Emitters (LAEs) at redshift 6.5, discovered inthe SXDS field within a large-scale overdense region (Ouchi et al. 2010). Thetotal GTC observing time in three medium band filters (F883w35, F913w25 andF941w33) is over 34 hours covering $7.0\times8.5$ arcmin$^2$ (or $\sim30,000$Mpc$^3$ at $z=6.5$). In addition to the two spectroscopically confirmed LAEs inthe field, we have identified 45 other LAE candidates. The preliminaryluminosity function derived from our observations, assuming a spectroscopicconfirmation success rate of $\frac{2}{3}$ as in previous surveys, suggeststhis area is about 2 times denser than the general field galaxy population at$z=6.5$. If confirmed spectroscopically, our results will imply the discoveryof one of the earliest protoclusters in the universe, which will evolve toresemble the most massive galaxy clusters today.
