With Reylorna and Jaldaric in the lead, and Salar the knight, Kylar
the legionairre following close behind, and the vordral guide just
behind them, the party advance down the side tunnel, towards the
sounds.  

The humming sounds get louder as they progress along the tunnel.  It
reminds Duplar of one of the larger Karazthani power generators that
requires fans to cool it.  

The tunnel appears to open out into a wider space, but before anyone
advances further, Reylorna hears voices.
