|Behind the scenes|
Castor's cane is a luminescent blue walking cane with a rounded grip on the top end. At face value, it appears to be something of a fashion accessory, adopted in accordance with Castor's propensity for extravagance. The cane serves no use for assisting Castor's balance and appears to be persistent in nature.
A hidden feature of the cane is its concealed gun weapon. The cane is capable of firing numerous high velocity light blasts in an automatic repeater fashion. These shots are damaging, at least to the point where they can harm objects and seriously maim a program. A single-shot blast, which may result from an alternate fire mode, is capable of derezzing a program with a direct hit at close range. Castor used this weapon feature to randomly spray gunfire all over the End of Line Club during a pitched battle, and later used it to derezz a Black Guard with a shot to the back.
- Similar canes were popularized by Fred Astaire, and Castor even imitates several of Astaire's performance moves including twirling his cane.
- Real life cane guns once served as a last resort weapon, although such devices were exceedingly rare.
- Eckert carried a similar cane, though its head was shaped differently and it had no known weapon capability.
