Thinking about it, I will give Elmund an invisible security detail, consisting of ten drones (same chasis as the one he had been developing and iterating on for quite some time now). Eight will be refitted, with Nova Blades instead of manipulators and technical tools on the 'palpus' and front 'legs' as well as nanites programmed to melt biological materials, to be injected via the 'fangs'. The other two will be the usual technician drones, but with upgraded AI package to accommodate 'demolitionist' and 'saboteur' programs.
All ten are usually out of sight, crawling through drains, pipes, vents and along ledges and rooftops. When staying in any premises for more than five minutes the technician drones will proceed to rig anything that can be rigged in the area in anticipation of 'Code Red'. Once 'Code Red' is initiated, all the rigged electronics, circuitry and machinery will short-out/explode/make alot of racket. The guardian drones will then exploit the opportunity granted to ambush the attackers from their hiding spots while Elmund escapes/whips-out-improvised-flamethrower/primes-and-throws-plastic-explosives-disguised-as-cigarette-boxes. If situation is too severe, Elmund will escape, initiate 'Code Black-A', upon which the technician drones will activate all the demolition charges (improvised) in response.
