Electrified Wall

The electrified wall was created during the Pagrir Unrest, invented by Athika Wilder. It was the invention which caught her the attention of the King of Kirvi, which led eventually to her reign as Sovereign of the Teardrop Sea Islands. Its bigger mark on history, however, is that it was the first electric-powered invention in the Mirror Lakes, paving the way for other (less deadly) uses.   The electrified wall proved to be a very effective outer layer of defence when under siege. Its use in the Pagrir Unrest by Kirvi was key to the kingdom's survival against its two rival kingdoms, and without it, would likely have been decimated and subsumed by them before peace could be brokered. There were notorious downsides, however; since the electricity could not be turned on or off, once it was set up, it posed a risk to anybody who touched it, not just the enemy.   Its first use was around the walled settlement of Dakiv, which was the target of approaching hoardes. Wilder had been studying electric blueberry plants for years, to figure out how the energy they generated worked. While the enemy was approaching, she came up with a rudimentry plan to repel them which utilised the potential she saw in the electricity.   The outer wall was criss-crossed with wire, including wrapping the wire around the metal spikes which had been added to the wall earlier in the Unrest. The wires were carefully laid according to Wilder's design, and then she had all the weeders dig up and re-plant every electric blueberry plant they could find inside the walls, connected to the wires. As a result, the enemy were unable to breach the outer defences, and Dakiv survived long enough for aid to arrive.   A slightly more refined version of Dakiv's electrified wall was used to defend Kirvi. Barbed wire was used this time, which meant it could tear holes in protective clothing to make anybody climbing the wall more exposed. Wilder designed a complex system of levers, made out of non-conducting materials, to be able to cut off power to the wall as needed. It was still far from a perfect design; three people died in the process of building it, but it successfully repelled most threats for years. While this took place before any method of measuring electricity was created, the amount generated was enough to kill around fifty percent of those who were shocked, and incapacitate everyone else.   The electrified wall has not been used since the end of the Pagrir Unrest. Part of the peace treaty, ironically negotiated by the inventor herself when she became Sovereign, was that all such defences be dismantled. It was classified as a wartime-only technology, and so while it could theoretically be used again in defence, the reality is that an electrified wall would not be nearly as effective against the modern level of technology.
