The next-generation of wide-field sky surveys, such as the Large Synoptic Survey Telescope (LSST), will revolutionise our understanding of the extra-galactic variable sky by discovering millions of transient objects every night. The key to fully exploiting this exciting science will be rapid spectroscopic classification of transients, combined with a systematic and unbiased follow-up strategy. The Time-Domain Extragalactic Survey (TiDES) has secured a quarter million fibre hours on 4MOST (4-metre Multi-Object Spectroscopic Telescope) to follow up LSST transients and their host galaxies. I will present an overview of the science aims and goals of TiDES, details on our current plans for rapid spectroscopic follow-up and my current and future involvement in this work.
