War of Ages continues to show Serenity perfecting their symphonic metal music and still keeping true to their power metal root. It also marks the first album with an additional singer, female vocalist Clémentine Delauney, formally of Whyzdom, and as it turns out a few years later, her last. This will also mark the final album of longtime guitarist Thomas Buchberger as an official member of Serenity. Both departures were announced via their Official website on February 3, 2015.
