Gao discovers the Emporer, still alive and grasping at a knife in his chest. Rushing to him and kneeling by his side Gao attempts us use his medical skill to preform first aid. the rules are very sketching on the scope of First Aid in RMU A&CL (Arms and Character Law).
I made the difficulty Very Hard (-20) and Gao rolls a 94 + 20 skill – 20 difficulty, a partial success, that should buy the Emporer some time. While Gao is working on the Emporer the doors to the apartments burst open and the Emporer’s body guard enter. They take one look at Gao covered in blood, knife in hand and the fallen Emporer. Putting two and two together in the way that only happens when PCs are around the enraged guards draw their swords and charge.
