On the final day, the Foxes were relegated to the Championship with a 2-1 win at home to West Ham not enough for them to escape the drop.
The outcome is damning, with Leicester once seen as one of the model teams to launch a consistent assault on the division's 'Big Six'.
To make things sting even more, they became the first team in the Premier League era to be relegated after achieving five consecutive top-half finishes.
There will be inquests into how such a devastating event was allowed to happen and there are plenty of factors old and new that contributed to the cost of their status.
A good point to start is the summer of 2021 after Leicester claimed a fifth-place finish and honours in the FA Cup, with it serving as an opportunity for the club to continue its momentum and cement its place towards the top end.
Patson Daka and Boubakary Soumare were brought in for relatively big fees but their talents did not translate on the pitch, while they went against their usual transfer mould with Jannik Vestergaard and Ryan Bertrand.
And unlike in previous windows, Leicester retained their star names which on the face of things was a bold decision but would end up being a detriment a year later.
Leicester finished the 2021/22 season in eighth place and enjoyed a decent run to the semi-finals of the Europa Conference League came before a big sliding doors moment in last summer's transfer window.
Manager Brendan Rodgers was in the process of looking to freshen up the side after regularly hinting at a need for signings. Said signings never arrived.
The club's finances were scrutinised by chairman Aiyawatt Srivaddhanaprabha, who said he had to make "difficult, short-term decisions" to "protect the club's long-term interests" and that meant any signings would need to be funded by sales.
They struggled to make those sales. There was tentative interest in Youri Tielemans with his contract running down but not enough for a transfer while Wesley Fofana, who was replaced by Wout Waes, and Kasper Schmeichel were the only departures late on.
The exit of Schmeichel would prove to be bigger than expected with Danny Ward thrust into becoming the first-choice in goal - something which he struggled to cope with.
Their heroic striker Jamie Vardy - now 36 years old - did not appear to be capable of reproducing his previously dependable scoring numbers with Harvey Barnes having to lead the way with 13 goals and James Maddison with 10.
While the squad had clearly gone stale, Leicester's set-up in games was significantly lacking and that fell on Rodgers, who was freefalling in the dugout.
Their 51 goals were the 10th most in the Premier League but defensively they were all over the place - from open play and specifically at set pieces.
Leicester did enjoy a decent period ahead of the World Cup which probably kept Rodgers in the job over the winter but it would only last into April when he was dismissed after a run of six games without a win.
Coaches Adam Sadler and Mike Stowell took brief control but the reality of relegation would start to loom large after Leicester suffered two home defeats to Aston Villa and Bournemouth under the pair.
Their manager search leading to Dean Smith would not come close to paying off with the former Villa and Norwich boss winning just two of eight games in the run-in.
Leicester's upcoming campaign in the Championship will be a period of adjustment for the club, specifically from a financial perspective given their squad is the most expensive to be relegated.
The parachute payments the club will receive will help in some form, but will they outweigh the departures of key players to chop down the wage bill?
Their most productive players in Maddison and Barnes are expected to command significant interest while Tielemans and Caglar Soyuncu are out of contract in June.
The off-season will be a time for self-reflection for all involved with the club before the fight to get back into the big time gets underway in August.
